DESCRIPTION
DVB- SI modulator in DVB-C. dmits MPEG TS input
G
signals in Packet or Burst format and deliveries modulated
signal in Q M. DVB- SI signal with digital programming
is converted to the RF band between 50.5 and 858 MHz
modulated in DVB-C. Handles MPEG-2 or MPEG-4 signals
enabling selection of programs delivered on output.

INST LL TION ND ST RT-UP
- The power sources must be disconnected from
the mains before connecting or disconnecting the
module.
Connect the earth connection of the frame to the earth
G
connection of the antenna installation.
Fix the modules to the frame in the order shown in the
G
application example (see page 3), with the power source
on the right and the amplifier on the left of the unit.
Join the RF channel outputs (8) via the F-F coaxial bridge
G
(Ref. 83814), and load the free output of module 1 with
75 , beside the power source.
Connect the Supply bus B 807 ref. 83807 between the
G
modules (5) and the SPS.
Connect the SI output cable to the corresponding
G
inputs (1) with 75
coaxial cables.
Connect the power source to the mains.

I
WORKING TEMPER TURE
The modules have to be refreshed for their correct
G
operationt. It's recommended to install the modules in
the housing with fan (Ref 83806) or, when installing on
a 19" rack, to use the Rack ventilation Unit (ref 83801)
When there are few modules to install, it's possible to
use the fan VNT 800 on the wall frame (fig N 1).

MODULES PROGR MM TION
The modules can be programmed:
Through the UCF 300 Control Unit (Ref 85115) in local
G
mode, following the steps explained in this manual.
Through a PC in local mode. In this case, it's necessary
G
to have a MCU 8000 unit and the "8000 series" interface
installed in the PC.

DISPL Y INDIC TIONS
The UCF 300 control unit has two rows of alphanumerical
characters. The data display mode and programming
diagram on page xx are a guide to this process:
If the characters are all upper case and on the upper

row, this indicates that one of the 5 functions has been
entered.
If data appear on two rows of the display, the
G
parameter to be adjusted is being displayed.
